CABLE-RACK.

To all whom it'mag concern .7

. insulators, and whichenables the insulators Be it known that I, Ja me KRAUS, .a citi- -zen.'of the United States, residing at Kimberly, inthe county of Outagamie and State, of Wisconsin, have invented new and use-- ful lmprovemen ts in Cable-Racks, of which thefollowing is a specification.

This invention relates to racks or. supportsforelectric conducting cables andfiinysulators, the object of the invention being to provide a rack adapted for general uses in.

supporting a plurality ofcables and their to bereadilyand conveniently applied and removed and an certain insulator or insulators be applie removed or had accessto withoutdisturbing the others.

A further object of the invention is to provide a rack'or support of the character described which byslight modifications may be adapted to support insulators and cables horizontally, vertically and at any desired elevation, and which is' adapted for the supportof eitherdirect oralternating current cables.- I I I The invention consists of the features of construction, combination and arran ement of parts herein fully described and c aimed,

reierence being-had tothe accompanying drawings in which v Figure 1 is aside elevation of a cable rackembodying my invention-.- Fig. 2 is. a .top

-In carrying my invention into practice I provide a rack comprising a top plate 1,

a bottom plate 2, and one or more intermediate plates 3. As shown in the present instance, the rack is: adapted to be secured to a ceiling or overhead support. and the top plate is provided with openings 4 for the .passage of bolts .or other suitable fastening devices, but, it will be understood, that the rack may by slight modifications be adapted for either vertical or horizontal use and to be supported'upon a floor, wall, ceihng or Specification of letters Patent.

any other suitable support at any desired elevation. The opposing faces of the res ec- .t1ve plates are provided with longitudinal seats for inconstructed channels or recesses 5 formin sulators 6, eachof which may in the usual manner of separable sections 7 i and 8, the arrangement being such that the insulators maybearranged and held iLn-rows I between the-plates,- as shown. Each intermediate plate is composed of two longitudinally divided sections 9 and 10 terminating in 006 crating pairs of hook-shaped projections orming split eyes 11 at the 0 adapted. to be held connected by detachable bolts 12 coupling the same adjacent to the eyes.- The top plate 1 is provided with end and central openings 13 and 14 receiving the upper ends of end and central supportin bolts or-rods 15 and 16, which are rivete or otherwise rigidly connected at their upper osite ends of the plate, the sections of whic are ends to said top plate and are threaded at their lower ends to receive retaining nuts 17. The bottom plate 2 is similarly provided with end and central openings 18 and 19 for thepassage of. said bolts and is held supported ,in position thereon by the nuts 17 The eyes 11 of the intermediate plates 3. I slidably engage the rods 15 and the sections 9 and 10,0f each oflsaid plates are provided with semi-circular recesses 20 forming an opening-for the passage of the central jbolt 16, thus enabling the intermediate plates and bottom late to be applied and removed b sliding it em on the rods whexithenuts 1 are detached. The rows of-insulat'o'rs-6 are arranged betweenlthe plates and clamped within the recesses 5 thereof, wherebythe sections of the insulators are held closed and .theainsulators and cables passing therethrough firmly fastened in position.

It will be understood that the sections-9 and 10 of each intermediate plate may be disconnected by removing the bolts 12 and said sections withdrawn laterally from the opposite sides of the rack.

When the rack is vertically disposed a convenient mode of assembling the sections, insulatorsand cables is to first apply the bottonrplate to the lower ends of the supporting bolts 0 rods, then fit the bottom sections 8 of the lower row of insulators therein, then place the cables in position in the grooves of said insulatorsectionsand place the top sections 7 of the bottom row of insulators in place, and then" apply the secbuilding up pursued until all the rack s'ecj tions are assembled and the insulaters and cables placed in position. When the insulators are so supported, it is evident that by,

the construction of the intermediate plates of detachable sections which may be re-' moved laterally, that any one of the insulators or cables may be arranged and withdrawn and reapplied, or any number of the insulator sections taken out without disturbing the'others. The insulator sections which come at the-center in proximity to the center bolt 16 are preferably provided with grooves 20 whereby they may loosely embrace the bolt and come closely together.

It will be-observed that the device forms a strong and .durable construction or sup port which may be made of any size to firmly and securely hold any number of insulators and cables. When the rack is used for cables carrying direct current all of the sections thereof, except the bolts, may be made of cast iron, but when used forcables carryin an alternating current, the base is made 0 .cast iron while the remaining parts are made of composition brass or other suit-' able material. In Fig. 10 I have shown'insulators 7 and 8 in the form of lining strips or plates, which may be used in conjunction with blocks of the construction shown in Fig. 9, which may or may not be formed of non-conducting material. The mode of employing these insulating plates or strips will be apparent from the foregoing description.

In Figs. 11 and 12 ,I have showna slightly modified construction of rack which is'designed particularly for v holding a small number of insulators'and cables. this construction the center bolt or rod and 'cooperating-features are dispensed with, the a construction otherwise be ng the" same as that previously described.

separable Iiclaimz v 1. A cable rack comprising outer plates, bolts fixed to one of said outer plates and with which the other outer plate is detachably engagingthe ,bolts,

connected, and anintermediate plate said plates being adapt-.

ed'to receive and hold insulators between the "faces thereof, the intermediate plate being provided with insulator retaining flanges and formed of separable longitudinal sections adapted to be disconnected and with- Idnliwn laterally from engagement with the 0 ts.

2. A cable rack comprising outer plates,

bolts rigidly connected withone of said outer plates and with which the other outer plate is detachably connected, an intermediate plate engaging the bolts, said plates having recesses in their opposed faces to receive and hold rows of insulators, the said intermediate plate being composed of longitudinal sections separably connected and adapted when detached to be withdrawn laterally from engagement with the bolts. M

3. A cable rack comprising outer plates, end and intermediate bolts fixed to one-of said outer plates and with which the other outer plate is d'etachably connected, an. intermediate plate engaging said bolts, said plates having recesses 1n their opposed faces to receive and hold rows of insulators, the intermediate. plate comprising longitudinal sections having notches for the passage of the intermediate bolt and cooperatingparts forming eyes engaging the end bolts, the construction being suchthat when the sections of the intermediate plate are disconnected said sections may be withdrawn laterally from engagement with the bolts.

In testimony whereofI afiix my signature in presence of two witnesses. g JAMES KRAUS.
